The eyeball includes a light-transmitting area for transmitting light. The back simulating member has a simulating surface being a first color. The front simulating member has a resilient capsule being a second color other than the first color. The resilient capsule is attached to the simulating surface, and arranged between the simulating surface and the light-transmitting area. The container is used for accommodating fillers. The at least one tube is capable of passing through the simulating surface to connect between the resilient capsule and the container. The driving member is coupled to the container for driving the fillers received in the container move towards and away from resilient capsule via the tube.

BACKGROUND

1. Technical Field

The present disclosure relates to replicas of human organs, andparticularly to a replica of an eye.

2. Description of Related Art

With the development of electronic technology, replica figures simulatethe actions of living creatures, such as walking and jumping. Becauseeyes can be so expressive in living creatures, they have received muchattention in the effort to allow replicas to simulate feelings. However,most replicas of eyes only open and shut which is not very expressive.Therefore, what is needed, are more expressive replica eyes.

DETAILED DESCRIPTION

Referring to FIGS. 1-3, a replica eye 10 includes a substantiallydome-shaped eyeball 100, a back simulating member 300, a frontsimulating member 200, a plurality of tubes 350, a cylindrical container400, and a driving member 500. The front simulating member 200 and theback simulating member 300 are received in the eyeball 100. Theplurality of tubes 350 is connected between the front simulating member200 and the cylindrical container 400. The driving member 500 is coupledto the container 400.

Referring to FIGS. 3-5, the eyeball 100 has a circularlight-transmitting area 102 capable of transmitting light. Thelight-transmitting area 102 is arranged on the front of the eyeball 100.In the embodiment, the light-transmitting area 102 is a transparentarea, and an inner surface 122 of the transparent area is flat. In otherembodiments, the eyeball 100 may define an opening in the front of theeyeball 100 instead of the transparent area 102.

The back simulating member 300 is shaped like a truncated cone havingtwo ends 310, 320 such as a first end 310 and a second end 320 oppositeto the first end 310. A diameter of the first end 310 is smaller thanthat of the second end 320. The first end 310 faces thelight-transmitting area 102 of the eyeball 100. The back simulatingmember 300 has a flat circular simulating surface 302 on the first end310, and the simulating surface 302 is recessed away from thelight-transmitting area 102 to form a receiving space 306 in the firstend 310. The simulating surface 302 is a first color. The backsimulating member 300 further defines a plurality of through holes 304connected with the first end 310 and the second end 320.

The front simulating member 200 includes an annular resilient capsule202 and a plurality of pipes 204 partially inserted into the resilientcapsule 202. The resilient capsule 202 is received in the receivingspace 306 and attached to the simulating surface 302. A diameter of thesimulating surface 302 is larger than or equal to an external diameterof the resilient capsule 202. The plurality of pipes 204, after passingthrough the corresponding through holes 304, connects with the pluralityof tube 350 correspondingly. The resilient capsule 202 is a second colorother than the first color.

The container 400 is used for accommodating fillers such as liquids,granular solids or gases. In the embodiment, the container 400 may be acylinder with a piston (not shown). The driving member 500 is used fordriving the filler received in the container 400 to flow through theplurality of tube 350 towards and away from the resilient capsule 202.In the embodiment, the driving member 500 may be a linear motor formoving the piston linearly to drive the fillers.

In use, referring to FIG. 6, the simulating surface 302 of the backsimulating member 300 simulates a pupil, the resilient capsule 202 ofthe front simulating member 200 simulates an iris. When the drivingmember 500 drives the fillers received in the container 400 to movetowards the resilient capsule 202, the resilient capsule 202 is dilatedin the receiving space 304, the simulating surface 302 viewed from theresilient capsule 202 is decreased, such that contraction of the pupilof the replica eye 10 occurs.

Referring to FIG. 7, when the driving member 500 drives the fillersreceived in the resilient capsule 202 to return to the container 400,the resilient capsule 202 is contracted in the receiving space 304, thesimulating surface 302 viewed from the resilient capsule 202 isincreased, such that dilation of the pupil of the replica eye 10 occurs.In this way the replica eye 10 is able to dilate or contract in a mannerrealistically simulating a living eye.

In other embodiments, the resilient capsule 202 may be disc-shaped tosimulate a pupil, and the simulating surface 302 simulates an iris. Whenthe driving member 500 drives the fillers received in the container 400to move towards the resilient capsule 202, the resilient capsule 202 isdilated in the receiving space 304, such that dilation of the pupil ofthe replica eye 10 occurs. When the driving member 500 drives thefillers received in resilient capsule 202 to return to the container400, the resilient capsule 202 is contracted in the receiving space 304,such that contraction of the pupil of the replica eye 10 occurs.
